Re: Eastern Tiger Swallowtail (P. glaucus) (dark phase/form)
Haha sorry Chuck, I misread your post. When you said you were unaware of a single dark MST, I misread that as “aware.” My bad.

Re: Eastern Tiger Swallowtail (P. glaucus) (dark phase/form)
In Butterflies of Canada, they mention the rare all black female canadensis found in NFLD. They reference Morris but I have never read the original source of this info, nor have I ever seen pictures of this. This sounds more like an occasional mutant than a distinct colour form that you can consiste...

Re: Bozano series Papilionidae IV published
One of the authors, V. Nazari, works at the CNC in Ottawa. He actually gave me a tour of their collection a few years ago when I visited. If all else fails, you can probably email him and he could probably tell you how to get the book in NA.

Re: Smerinthus cerisyi variations
Is the variation clinal? I wonder if anyone has looked into the genetics to see if they should be different subspecies?

Re: mature larva behavior
No, not all species have a liquid dump. Some have one last pellet that’s sort of loose. Others have more or less normal frass until the very end.

Re: Osmeteria of P. rumiko
Yes, based on your location, you have rumiko. All the cresphontes I have seen have bright red osmeteria.

Re: Osmeteria of P. rumiko
The osmeterium of P. cresphontes is bright red. Is the color difference with rumiko consistent?

Re: Permathrin- kills more than just ticks
Permethrin acts on neurons. It interferes with sodium channels to disrupt the function of neurons, and causes muscles to spasm, culminating in paralysis and death. It is not a carcinogen. I have never used it because I am not out much, but it does not seem too worrisome. Skin absorption is low, abo...

Re: Tiger Swallowtails of NY: Finger Lakes, Part II
Yeah, seems to be an exceptionally good year for them. The long and thin tail is a great aberration on that specimen. I also noticed the claspers before seeing your comment. This is a canadensis-like trait. It used to be thought that MST had pure yellow claspers, like glaucus. But now it seems that ...

Re: Any Thysania agrippina experts out there?
If the purpose of the frenulum is to couple the fore and hind wings, why is it that when we pin and spread a moth, positioning the forewing doesn’t automatically move the hindwing up? Is the coupling just that weak? As for why males and females differ, Chris Grinter discusses a possible hypothesis o...

Re: Observation -> proposal -> sanity check: Papilio puddling/ ground feeding
I don’t have an answer, but it seems reasonable to posit that they puddle as soon as they can to load up on mineral salts, and once they have fuelled up, this could last them a long time (perhaps they only need to do this once?).

Re: Laurel Swallowtail (Papilio palamedes)
Years ago when I was in Florida, I found 2 eggs on Persea. Unfortunately both were parasitized by small wasps.

Re: Tiger Swallowtails of NY: Finger Lakes, Part II
No brevicauda, very frustrating. I went to 3 dunes, perfect habitat, abundant food plant, but no eggs, larvae, empty eggshells, or evidence of leaf damage from caterpillars. I am not bad at locating eggs/caterpillars. In fact, I think I am pretty good at this. However, I couldn’t find anything this ...

Re: Clear, self ballasted, 450w M.V. Bulbs
I was in New Brunswick this week. Not being able to locate a clear self ballasted MV bulb, I bought a 50W LED light at 365 nm. I did not get a spectral analysis and I have no side to side (or even night to night) comparison with incandescent, MV, or MH light sources. With those caveats out of the wa...

I am in New Brunswick right now. Peak canadensis season it would seem. Saw several driving today and even hit one. None captured. No ova located. The hunt continues.
